STORM VENTILATOJR, FOB. WINDOWS.

Application filed March 28, 1922. Serial 1*1'0. 547,409.

storm ventilator for windows, the same being adapted to be clamped to the lower sash of a window so as to allow proper ventilameans for detachably securing the same to tion and particularly, as one of the objects, so that in stormy weather, fresh air can en- .ter a room to the exclusion of the rain or snow.

A further object is to render the ventilator adjustable to suit windows of different widths and to provide novel clamping means for securing the device detachably in position and to accommodate sash frames of different thicknesses.

These objects, and other advantageous ends which will be described hereinafter, I attain in the following manner, reference being had to the accompanying drawings in which Figure 1 is an outside elevation of a window having the improved storm ventilator applied to the lower sash thereof,

Figure 2 is a perspective view of the improved storm ventilator, and

Figure 315 a vertical sectional View taken on the line 3 3 of Figural, the parts being enlarged as in Figure 2. i

Referring to the drawings in detail, in which for purposes of illustration is shown the preferred embodiment of the invention, and in which like reference characters designate corresponding parts throughout the several views, it will be seen that the ventilator .includes two sections 10 and 11 which are made of suitable sheet material, preferably of a bendable or flexible nature, such as sheet metal and bent into the form illustrated. The section 10 has one edge bent upwardly at right angles to form a clamping flange 12 and the section 11 is correspondinglv bent to form a clamping flange 13; the upper edge of the flange 12 being re-bent or turned as indicated at 14:, so as to extend forwardly and downwardly in spaced relation to the flange 12' and form a groove or guide for slidably receiving the upper portion of the flange 13 of the section 11, which slidably fits therein.

The section 11 has its free or forward edge turned downwardly and rearwardly as indicated at 15 corresponding to the turned portion or edge 14 so as to embrace the front or free edge, portion 16 of the section 10 so as to slidably hold the two sections together in substantially telescopic relation. so as to allow them to be extended or contracted whereby the ventilator may beadjusted in length to suit windows of various sizes or widths.

Each of the sections is provided with flanges 12 and 13, as it is thought will be readily understood upon inspection of the drawings. The intermediate or bottom portions of the clamps 17 after passing through the openings 18, are slidably held beneath guideways 23, preferably in the form of small metal strips securely fastened to the top faces of the sections 10 and 11 so that the clamps can freely slide back and forth in order that when the screws are tightened up, the ends or jaws 20 of the clamps on the outside of the window sash will readily move up against and clamp the sash, thus clamping the ventilator securely to the window sash and allowing the ventilator to move up and down with it so as to make practically a tight contact when the sash is down or closed.

In illustrating the application and use of the device, there is shown in the drawings a window frame 24 having a sill 25, the frame slidably receiving the upper sash 26 and the lower sash 27 to the bottom rail 28 lilo . and especially sleeping rooms.

commodate themselves to the thickness of different windows. a

It will thus be manifest that a storm ventilator constructed as described is not only practical and useful but is durable and in a sanitary way essential, since windows may be kept open in rainy or snowy weather, thus facilitating the ventilation of rooms Of course, the device may be used at any time and will effectively prevent rain or snow from entering the room in addition to permitting 'proper ventilation or airing at all times and which is not possible when the window is not equipped with such a device, owing to the damage which might be caused by the rain or snow entering the room while the window is open.

The device preferably has the sections 10 and 11 extending out from the window so as to form a shed, for the purposes just described and preferably curved slightly downwardly as indicated at 29 in furtheranoe thereof. It will also be obvious that the ventilator may be easily and readily attached to the window sash and does not interfere in any mannerwhatsoever with the raising or lowering of the sash with the ventilator attached and to any height desired, depending upon the severity of the weather. The device is also not objectionable since when attached to the window, it will not mar the same and being painted or enameled is neat in appearance and inconspicuous. It will also be obvious that the construction shown and described is susceptible of application to the top of the window frame or upper sash and that I do not desire to be restricted in the use and application of the invention although I have set forth what I now considerto be the preferred construction and use thereof.

changes and alterations as fairly come within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. A storm ventilator includinga sheet; a clamping flange onthe sheet, and clamps slidably secured to the sheet and having iheir jaws disposed at opposite sides of the ange.

2. A storm ventilator including a sheet; a clamping flange thereon having openings, and clamps passing through the openings and slidably secured to the sheet. v

3. A storm ventilator including sheet sections adjustably secured to each other; clamping flanges thereon having openings, and clamps passing through the openings and slidably secured to the sections.

4. A storm ventilator of the class described comprising a pair of slidably fitted sections having downwardly curved portions at one edge and upwardly directed portions at the other edge, said, upwardly directed portions having holes through the same; guides 'on the sections adjacent to said holes; clamps having bottom portions slidable through the holes and guideways and having jaws upon opposite sides of the upwardly directed portions; and clamping screws engaged through certain of said jaws.

5. A storm ventilator for windows comprising a sheet-like structure having an upwardly directedportion; U-shaped clamps slidably mounted through said upwardly directed portions and retained against the upper surfaces of the'sheet-like structure; guide strips upon said sheet-like structure for receiving the clamps, said clamps having jaws u on opposite sides of the upwardly directe portion; and clamping screws engaged through the inner jaws to contact with the upwardly directed portion whereby the ventilator may be clamped to the sash between said upwardly directed portion and the other jaws.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
